Publication number: 20100246371Abstract: According to a first aspect of the invention, an optical information recording apparatus includes a spatial beam modulator, an optical component, a drive unit, and a control unit. The apparatus performs angle-multiplex recording of the information so that an absolute value of a bisector angle ?x for n-th recording (1?n?rN) is smaller than an absolute value of a bisector angle ?x for m-th recording (m>n and rN<m?N). Here, N is the number of pages to be defined as the total number of recording times performed on a recording spot of an optical information recording medium. The n-th recording is performed on the recording spot with the reference beam and the information beam. r is a rate to be determined by a volumetric shrinkage of the optical information recording medium. The volumetric shrinkage increases with irradiating the optical information recording medium with the reference beam and the information beam.Type: ApplicationFiled: March 8, 2010Publication date: September 30, 2010Applicant: KABUSHIKI KAISHA TOSHIBAInventors: Masahiro Kanamaru, Kazuki Matsumoto, Rumiko Hayase, Yoshiaki Kawamonzen, Norikatsu Sasao, Masaya Terai
